准实验研究

The maesurement errors in the laser collimation are mainly caused by the light beam drift, the light beam incurve and the light beam random tremble.

论文中对长距离激光准直光束特性进行了较详细的实验研究和理论分析认为，影响其准直精度的三个重要因素是光源漂移、光线弯曲和随机抖动。

The offset of the beam position monitor with respect to the magnetic center of the quadrupole can be determined by the method of the beam-based alignment.

The "nonequivalent group pretest-post" quasi-experimental design was used for the study.

本研究方法采「不等组前测－后测」之准实验设计，以国立彰化高级中学90学年度二年九班44人及二年十五班46人，共90名学生为研究对象，依序分为实验组、控制组，实施为期七周14小时的实验教学。

The design of nonequivalent pretest-posttest control group, as quasi-experiment design was applied to the study. There were totally 67 seventh students from a junior high school in Taipei county participating in this study, 34 of which were assigned to the experimental group and 33 of which to the control group. Students in the experimental group went through 24 sections emotional education into the integrative activities for 8 weeks, 3 section（135 min）, per week, while those in the control group accepted the original integrative activities curriculum.

研究方法采不等组前后测准实验设计，以台北县某国中67名七年级学生为研究对象，实验组共34位学生，控制组共33位学生，实验组接受为期八周，每周三节课（135分钟），共二十四节课的实验课程处理，控制组则接受原综合活动课程。

This study is a kind nonequivalent pretest-posttest designs of quasi-experiment in life education. The experimental group is the six grade class led by the researcher, and the control group is another six grade class of the same school. The researcher executes analysis of covariance of the grade school pupils' life attitude evaluation scale and quality data, in order to explore the meaning, value and feasibility of life education. The researcher wishes to become the reference for someone who wanted to work about the life education by executing the curriculum of life education.

本研究是以实施生命教育课程为主的不等组前后测设计之准实验研究，以研究者实际教学的六年级班级为实验班，另一六年级班级为对照组，进行「国小儿童生命态度量表」前后测的共变数分析，辅以质性资料的分析，来探讨生命教育课程的意义与价值及其可行性，希望能透过研究者对於生命教育课程的实践，成为日后有志从事生命教育工作之参考依据。

The design of extracurricular reading project adopts the nonequivalent pretest-posttest quasi-experiment with the subject of 53 children at grade 3 in Taipei City elementary schools for 6-month reading activity research.
